Bhagavad Gita 5.12
युक्तः कर्मफलं त्यक्त्वा शान्तिमाप्नोति नैष्ठिकीम्।अयुक्तः कामकारेण फले सक्तो निबध्यते॥
yuktaḥ karmaphalaṃ tyaktvā śāntimāpnoti naiṣṭhikīm |ayuktaḥ kāmakāreṇa phale sakto nibadhyate ||
The one who is united (the well-poised or harmonized) having abandoned the fruit of action attains eternal peace; whereas the one who is not united (the unsteady or unbalanced), impelled by desire and attached to the fruit, is bound.
Having abandoned the fruit of action, he wins eternal peace. Others, unacquainted with spirituality, led by desire and clinging to the benefit they think will follow their actions, become entangled in them.
Our plain-language meaning of this verse is waiting for scholar review.
